This is the 1981 Turing Award and does not contain any "rules", numbered or not.
According to his lecture, the "original definition of the relational model" appeared in
E.F. Codd, A Relational Model of Data for Large Shared data Banks, Communications of the ACM 13, 6 (June 1970), 377-387
and "an improved version" in
E.F. Codd, Extending the Database Relational Model to Capture More Meaning, ACM Transactions on Database Systems, 4, 4 (December 1979), 397-434.
(Both papers are in the ACM digital library).
You can find "Rules 1 - 7" in the second of these papers, however, these are not "Codds Rules" as understood today and cited above by CELKO. So I think your question is still open. I'm interested in an answer, too!
